Network adapter issues

Okay so my problem is is that the adapter i have is a Edimax Ew7811un and i notice that it connects to the WiFi fine, and then a few minutes later it goes to limited, thought it was a port issue so i change it to a different port, same thing, i've tried another adapter from TP-Link and it still does the same, tried both adapters on my desktop and both work pretty much fine, been like it for the past few days,any tips?

Any help is appreciated as always :)
